Error Code: 0xe0434f4d

P: 6
I have written a windows forms app, for .net 3.5 sp1, I have dployed this OK to a Vista machine but it fails to run on an XP machine. It generates the above execption code.

I initially thought this was a .NET security issue but the app was installed from the local physical disk and is a fully trusted app.

Anyone any ideas ? (I have deployed other apps to both Vista and XP before using the same security??)

Does the XP machine have the correct version of .NET installed?
Are you using any third party DLLs or COM objects in your project?

It had 35 on it so I have now created a fresh XP install (in a VM) with 35 SP1 on it. Now the prog starts for a second or two and dies without any messages. I checked by running filemon and it did start but very brioefly. No window ever appears.
I am not referencing any third party dlls or com objects.
is there some compatability issue here or am I right to expect this to work ??

New development, I have now installed VisualN Studio onto the oroginal XP machine. The prog now starts! This happens both if I run it from within the IDE and if I use the copy I had already installed on the OS.

There must be something that VS installs on the OS that I am depending on but I have no idea what !

Are you using anything in the VisualBasic namespace? Becuase that requires a special runtime.
Otherwise I am not sure why installing VS would help, unless it installed an older version of .net (1.1 or 2.0 or 3.0) that maybe is just expected to be there
